MOTOR.

SPECIFICATION forming part of Letters Patent No. 509,052,.dated November21, 1893.

Application filed March 13, 1893- such as will enable others skilled inthe art to which it appertaius to make and use the same, reference beinghad to the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention relates to improvements in pump operating mechanism, andthe object of the inventionis to improve the machine described inLetters Patent of the United States, No. 489,419, issued to me, bearingdate January 3, 1893, and to this end the mechanism consists of thefeatures, arrangements and combinations hereinafter described andclaimed, all of` which will be fully understood by reference to the vaccompanying drawings, in which is illustrated an Vembodiment thereof.

In the drawings, Figure lis a side elevation of the mechanism. Fig. 2 isa top or plan' view of the operating parts, the upper portions ofthemechanism being removed. Fig. 8 is a plan View of the base of themachine, illustrating the pump cylinders and showing their connectionswith the central chamber. Fig. 4 is a top or plan view of the machine,the adjustable top frame being partly broken away. Fig. 5 is afragmentary view in perspective of the movable spring actuated platewhich returns the pivoted arm to itsupward limitofmovementaftereachdownwardstrokel` Fig. 6 is a fragmentary view in perspective of one ofthe pivoted arms which operate the pumps.

Similar reference characters indicating corresponding parts or elementsof the mechanism in the several views let the numeral 5 designate astationary base supporting the pump cylinders 6, connected with thesupply source by pipes 7 and provided with outlet conduits 8, leading tothe central receiving chamber 9, provided with a discharge pipe 10 atthe bottom. .The piston rod 12 of each lpump cylinder is movablyconnected at its sean no. 465,835. (No man.)

upper extremity with an arm 13 provided with 1acurved shank 13a thatpasses under the outer ous construction it is necessary to out away thematerial of the platforms rim, whereby lthe latter is greatly weakened,in order to .form suitable recesses for the reception of the armsattached to the pump pistons. By forming the arms curved, and passingthem under the rim as in my present construction, I avoid vthe necessityof forming recesses inl the rim, since the free extremities of the armsare interiorly located with reference to the rims inner circumference.Hence the rim of the platform remains intact and at the same timelaffords the support for the arms. The platform 1'4 is supported by legsor standards 16 connected with the base 5. Movably connect- 'ed with theouter extremity of arm 13, is arod vv17 forked at its lower extremity,as shown at -17a and secured to a vertically movable plate 18 aperturedat each extremity as shown at 18, and carrying depending sleeves 18. Theopen'ings'in these sleeves coincide with the apertures in the platewhich is supported by coil-springs 19 which are attached to theextremities of plate 18 outside of theguide rods 20 and to the platform14 above. These guide rods pass through the apertures in plate 18 aswell as the depending sleeves which give the plates an elongated bearingon the rods which are stationary and secured between lthe base 5 and theplatform 14. Suitably secured to the top platform 14 and supportedthereon, are the vertical rods 22, passingv through suitable aperturesformed in the lugs 23 projecting exteriorlyfrom the rim 24, providedwith radialarms 25a, and centrally guided and retained in place by thepost 26 journaled upon platform 14. The rim 24 is IOO The function ofthe rim 24 and rollers 25 is to maintain the wheel 27 in operativerelation with the disks 35hereinafter described.

Tere it not for said rim and its rollers, the cogged portion of thewheel 27 might under some circumstances slip from engagement with theperipheries of said disks, by virtue of theyielding quality of the metalcompose ing the wheel which without the mechanism in question, wouldhave only the post 26 to maintain itin operative relation with thedisks. It is believed that the length of the wheels radius would be suchthat it would be unsafe to rely vupon the Wheels rigidity to maintain itat all times in engagement with the disks mentioned.

Thecogged periphery of wheel 27 is engaged by a pinion 29 made fast tothe upper extremity of a vertical shaft 30 provided at its lowerextremity with a bevel pinion 31, meshing with another similar pinion 32made fast to a short horizontal shaft 33 journaled -in ya box 34 securedto the base 5.

Power is applied to the machine by rotat ing the shaft 33 which isprovided with a pul- V ley 34a `which may be connected with any l innerportion of whoseface is smooth as shownj at 35c to make a proper bearingtherefor.'

suitable motor.

Wheel 27 is supported from below by the disks 35 which are pivoted uponthe periphery of a horizontal wheel 36 made fast to post 26 and rotatingtherewith. Disks 35 are of a ydiameter equal toi the distance betweenwheel 27 and the platform 14. The outer part of the face of disks 35 iscogged as shown at 35a to engage the correspondingly cogged` track14aformed upon platform 14. The arms 13 lie in the path of the disks 35,the

Thesmooth portion of the disks'face does not engage the rim but projectsover its inner circumference to engage the arms 13 which lie in theirpath. The outer face of rim 36 is also provided with smaller lrollers ordisks 41 and 42 suitably pivoted on the rims. The rollers 35,41 and 42are arranged on theirsupporting rim in setsfor groups, each 'setconsisting of one roller of each kind. Of these rollers or rotatingdisks, 35 is the largest, 42 the smallest and 41 of an intermediatesize. There are four sets of these roll-l upon each arm 13 during eachrotation of the wheel36, whereby these arms are depressed so that they-lie in the same horizontal plane with the upper surface of platform 14,the

of the piston rods.

4piston'rods 12 being correspondingly depressed. The rim 36 is rotatedin the direction indicated by the arrows in Fig. 2, whereby rollers 42,or the smallest rollers of each set engage and act upon the arms 13,first, giving them a partial downward movement, then follow therollers`41 next in size which act to further depress the arms, afterwhich f the disks 35 complete the downward movement of the armsand thecorresponding stroke It will thus be seen that by reason of the coggedconnection between thel disks 35 and the rim 36, the power 1s `much moreefficiently and advantageously applied than when this connection issimply frictional asshown in my previousl patent.

The rods 17 and their plates 18 are alsosimultaneously and correspondingl ydepressed, the springs19 being stretchedor placedaunder tension bythe downward movement of` said plates. As soon asv the last roller-(35)of any set leaves the arm 13 the latter is immediately returned to itsvupward limit of movement through the-medium ofrod 17 and plate 18'which is suddenly carried upward 'by the recoil of springs 19, to itsoriginal position ready for engagement by t-henext1setof rollers. Y

' It will thus be seen that my present construction is materiallydifferent-from that shown in Patent No. 489,419 and it is believed thatimportant advantages are gained over the mechanism previously-patented,not-only from a standpoint ofsimplicity and economy of construction, butalso in pointsofiefiiciency `and general utility.

Having thus described my invention, what I claim is 1. In a mechanicalpower, the combination of a suitable framework composed'of abase y,andan upper platform supported thereon, of one or more inclinedarms,pivoted ontheupper platform atene extremityand supported byspring-actuated rods at the'other extremity, and a horizontally rotatingwheel made 'fast to a vertical shaft j ournaled-in the framework and oneor more Adisk-s pivoted on-the peripheryvof said wheel, the lface ofthese Vdisks being partly cogged and partly smooth,

the cogged portion engaging a cogged track formed kon the stationaryplatform, while the `smooth part engagesl the inclined arms which areIforced downward against the upward tendency of the spring-actuatedrods, which impartto the arms the -upward movement-as vsoon as the disksleave them, substantially as described.

2. In a mechanical power, the combination of a suitable frame-workhaving acircular cogged track, one or moreoscillatin'g arms `pivoted onthe'frame-work, a horizontallyroers shown in the'drawings and each setacts tating wheel mounted on the `frame andcarrying one or more pivoteddisks having a @Ogged face to engage the track on the frame',

` frame, a power wheel made fast to the shaft,

another wheel also made fast'to the shaft and carrying disks pivoted onits peripheryn'such disks having acoggedyface to engage tracks rformedon the power wheel and stationary' frame, and a plain face to engage thearms, substantially as described. 'l v 4. In a mechanicalpower, thecombination of a suitable stationary frame-Work, oscillatingarmspivotedthereo'n and means for movingsaid arms in one direction,consisting of stationary rods, a plate slidingly supported thereon,coil-springs attached to the plate and to thel stationary platform, andanother rod connected with the plate at one extremity,

and with t-he oscillating arm at the opposite extremity, substantiallyas'described.l

5 In a mechanical power,`the` combination of the stationary frame, the'oscillating arms pivoted thereon, and means for imparting to said armsmovement in one direction, consisting of a horizontally rotating wheelmounted on the frame-work, andV carrying a set of disks of dierent sizespivotedpon the rim, and adapted to successively engage the arms, thelargest of these rollers being pro vided with a cogged face to, engage atrack formedon the frame, and a'plain face to engage the arms,substantially as described.

In testimony whereof I aftix my signature in presence of two witnesses.
